# Write a Python function to to determine if a number is a perfect number.
"""
Perfect number number that is half the sum of all of its positive divisors
(including itself).

for example : if the number is 6:

1 is divisible by 6
2 is divisible by 6
3 is divisible by 6
4 is not divisible by 6

even 1+2+3=6 which is also divisible by 6
